pixels stores the pixmap data. pixelsToFree is either 0 or some memory | |

release callback has been called. There are two uses to pixelsToFree: | |
1. If pixels == pixelsToFree, then we know that the CGImageRef is done\ | |
with the data and we can modify pixels without breaking CGImageRef's | |
mutability invariant. | |
2. If pixels != pixelsToFree and pixelsToFree != 0, then we can reuse | |
pixelsToFree later on instead of malloc'ing memory. | |
